Allocation dynamique sur cloud IaaS : allocation dynamique d’infrastructure de SI sur plateforme de cloud avec maîtrise du compromis coûts/performances

Abstract : In the field of cloud computing, IaaS provide virtualized on-demand computing resources on a pay-per-use model. From the user point of view, the cloud provides an inexhaustible supply of resources, which can be dynamically claimed and released. IaaS is especially useful to execute scientific computations using operating budget instead of using a big initial investment. Provisioning the resources depending on the workload is an important challenge, especially regarding the big number of jobs and resoruces to take into account, but also the large amount of available platforms and economic model. We advocate the need for brokers on the client-side with two main capabilities: (1) automate the provisioning depending on the strategy selected by the user and (2) able to simulate an execution in order to provide the user with an estimation of the costs and times of his workload's execution. Many provisioning strategies and cloud providers can be used in this broker thanks to its open architecture. Large scale experiments have been conducted on many cloud platforms and show our tool's ability to execute different kind of workloads on various platforms and to simulate these executions with high accuracy.
